IMPROVEMENT IN MACHINES FOR TURNING HEEL-RANDS.

Specification forming part of Letters Patent N0. 138,257, dated April29, 1873; application filed December 10, 1872.

v To all whom it may concern:

Be it known that we, JOSEPH B. JOHN- soN and GEORGE W. MoULToN, of Lynn,of the county of Essex and State of Massachusetts, have invented a newand useful or Improved Machine for Turning Heel-Bands; and do herebydeclare the same to be fully described in the following specification,and represented in the accompanying drawing, of which- A Figure 1 is atop view; Fig. 2, a side elevation; Fig. 3, a front-end view; and Fig.4, a vertical and longitudinal section of such machine. Fig. 5 isfront-end view of its randtnrner. Fig. 6 is a side view, and Fig. 7 atransverse section of a rand as it appears before being turned by themachine. Fig. S represents the rand as turned.

In the drawing, A denotes the abutment or base, with which therand-turner B operates. This rand-turner consists of a circular head, a,and an arbor, b, arranged as shown, such `head being convex, andprovided with radial teeth o upon its outer surface or that next theabutment. The rand-turner B is arranged concentrically in a box or case,D, fitted to slide upon two parallel rods, E E, projecting from theabutment and connected by a cross-head, F, all as shown. Fig. 9 is atransverse section of the case D, such section being taken through thehead a, and the rand guide-chamber d within which it is arranged. Thischamber is circular in sect-ion and concentric with the head ct, and isprovided with a mouth, e, formed through its periphery, as shown, an endview of the case D being represented in Fig. 10. Within the case D, orthe chamber g thereof, is a helical spring, f, which encompasses thearbor b, and bears at one end against the head a, and at the otheragainst the rear end of the said chamber g. Furthermore, there may be adischarging-opening, h, made in the abutment, or arranged therein asshown. The arbor b goes through a tubular screw, G, which screws intoand through the crosshead F, and against the rear end of the case D, andis provided with an arm, i, the latter being extended from the screw inmanner as represented, and close to a crank, El, fixed upon the arbor b.The spring f serves to keep the rotary turninghead a pressed against therand, while the latter may be in the act of being turned. It also servesto effect the discharge of the rand from the guide-chamber, or to pressthe case back upon the arbor of the rand-turner while the screw is beingturned back, and until the arm t' may bring up against the crank.

In using the machine the case is iirst to be forced up into contact withthe abutment. Next, the rand, at one end, is to be introduced into themouth c of the guide-chamber d, and between the abutment and the teethof the head ct, after which the crank is to be turned so as to revolvethe part B. This will cause the rand to be driven around within theguide-chamber d, andbent in a circle. Next7 the arm t and the crank areto be simultaneously turned backward until the head et may be forced outof the randchamber, and

drawn far enough away from the abutment v for the rand to fall or bedischarged from between the two. The rand after being bent may bedischarged through the opening in the abutment. To effect this theattendant has only to watch for the end of the rand to make itsappearance at the said opening, and to seize such end turn it outwardthrough the opening, when the continued rotary motion of the head t willcause the rand to be discharged through the opening. While such adischarge may be taking place a fresh rand may be inserted in the mouthof the rand guide-chamber and be in the act of being turned. Theabutment is provided with a lip or base, P, by which it may be fixed toa table or work-bench either by screws or suitable clamps, the inneredge of the abutment being adjusted in the vertical plane of the edge ofthe table or bench.

In practice the machine is exceedingly eficient for the purpose ofturning rands.

We claim as our invention as follows, viz: 1. The combination of theabutment A, provided with or being without the discharging-passage h,the rand-turner B, the case D, having the rand turning and springchambers, as shown, the spring f, the screw G, provided with a mouth, e,for reception ofthe the cross-head F, the arm i, and the crank rand, asset forth. l

H, al1 arranged and combined essentially in JOSEPH B. JOHNSON. mannerand to operate as and for the purpose GEORGE W. MOULTON. specified.

2. The combination of the abutment A and Witnesses: the dischargeopening h thereof With the R. H. EDDY, rand-turner B and the randguide-chamber d, J. R. SNOW.
